Hi JulieAnne
After I went to the first doctor, a female, who said there was no way that the bleeding was related to the Canestan, I went to the surgery again and saw a male doctor, who ironically was far more understanding of the situation.
He felt that this unexpected bleeding, in a woman who was usually very regular, was highly UNLIKELY to be a pure coinsidence. He felt that it was more likely to be a reaction to the medication. He then put me on a course of tablets (Apologies, but I don't recall the name) which basically take charge of the cycle and stop the bleeding. He said it was the same medication that he would prescribe if a female was going on holiday and wanted to ensure there was no menstration. The tablets worked a treat and everything was back to normal. He also gave me an alternative treatment with a different active component to get rid of the thrush.
I am sensitive in that area of the body and am prone to irritation etc, and I had noticed that after using a Feminine wash with Canestan I also felt irritated and a bit swollen down below, so I genuinely think that some ladies have an intolerance to the active product in Canestan.
There are alternatives out there which your doctor can prescribe which are made with a different ingredient but have the same effect without the nasty reaction.
After reading the other blogs on this page, I wrote to Canestan who did appear concerned and within a couple of days I had a questionnaire from them asking for full details. Hopefully, if more ladies do this, they can advise about this side effect which if nothing else, will avoid the alarm we've all experienced when we have such bleeding afterwards.
JulieAnne, if it's any concellation, the second GP reassured me it was nothing to worry about, just a trigger reaction to the medication and since then, having avoided Canestan, the symptoms have never reoccurred.
I hope this helps, Bank Holidays are an awful time to have problems as you can't get to any surgerys! All the best.
